MARKING-POT.

SPECIFICATION forming part of Letters Patent No. 621,400, dated March21, 1899.

.Application filed March 15, 1897. Serial No. 627.550. (No model.)

To all whom, t may concern.'

Be it known that I, ANDREW J. BRADLEY, a citizen of the United States,residing in the city of St. Louis, in the State of Missouri, haveinvented a new and useful Marking-Pot, of which the following is aspecification.

My invention relates to ink-pots or paintpots. Its principal object isto insure the proper inking of the marking-brush; and it consists in apot having a ball or 4similar device arranged to be partly in and partlyabove the ink, so that the turning ofthe ball will bring Aa thin lm ofink into position to be available for inking the marking-brush.

In the accompanying drawings, which form part of this speciiication,Figure 1 is a plan view of my device. Fig. 2 is a side view thereofinline with the axle, a portion of the side being broken away to show theinside arrangement; and Fig. 3 Ais a vertical section on the line 2 2 ofFig. 1.

The body of my device is a pot or cup 1, of any suitable shape andmaterial. Inside of said pot is a ball 2 or roller, arranged to have itssurface dipped into the ink or paint and then be raised above the levelthereof. The ball or roller 2 is mounted on an axle which works injournal-bearings 3, provided therefor. These bearings are preferablysuspended from the cover 4. The latter construction is much easier toclean and alfords a very convenient means of adjusting the ball to thelevel of the ink or paint.

Divers means of adjusting the height of the ball may be used. Thedrawings illustrate a device consisting of a flange 5,depending from thecover and tightly fitting inside the pot or tank, so as to stay at anylevel to which it may be adjusted.

The cover l is slightly inclined or funnelshaped and has a central holethrough which the upper portion of the ball or roller eX- tends. Thesize and shape of the hole are such as to leave a very small spacebetween the ball or roller and the margin of the hole. The size andinclination of the cover are such that it serves both as adaubing-surface and for returning the surplus ink into the tank. Asmaller hole -6 in the cover serves for taking the height of the ink orpaint for refilling and for admitting a marking-brush.

n The operation of the device is as follows: The pot being filled withink, paint, or other, liquid to the desired level, the ball or rollerrests partly below and partly above the level of the liquid. The paintormarking brush is then brushed repeatedly over the ball or rollertransversely of its axle, with the result of turning the same. As theball or roller turns the portion formerly below the ink rises, carryinga iilm of ink into position to be rubbed off onto the brush. As thisoperation continues the top portion of the ball or roller rst dips intothe ink, then rises with its coating of ink, which is largely removedonto the brush, then again dips into the ink, and so on. The brush isthus inked thoroughly with# out being sopped. This result is of specialimportance for stencil-marking, as a very little superfluous ink in thebrush is liable to run and blur the stencil-mark.

What I claim is- 1. A marking-pot comprising a pot, a cover thereforwhich inclines slightly downward to a centrally-located hole,journal-hangers depending-from said cover, and a ball or roller mountedon an axle journaled in said hang-- ers and having its uppermost portionproject slightly through said hole close to the edge thereof, .the sizeand inclination of said cover being such that it both sheds the surplusink back into the tank and serves as a daubingsurface, all substantiallyas and for the purpose set forth.

2. Amarking-pot comprising a pot, a cover inclined slightly downward toa central hole,

journal-hangers depending from said cover and a ball or roller mountedon an axle jour.- naled in said hangers and projecting slightly throughsaid hole, said ball being of such size that it just clears the edge ofthe hole, said cover having a downward marginal flange tting into thepot, whereby said cover and ball may be adjusted vertically, the sizeand inclination of said cover being such that it both sheds the surplusink backinto the tank and serves as a daubing-surface, all substantiallyas and for the purpose setforth.
